' B'OB-SLED.

SPECIFICATION forming pari'.` of Letters Patent No. 549,402, datedNovember 5, 1895.

Application filed June 8, 1895. Serial No. 552,072. (No model.)

T0 all whom it may concern: Y

Be it known `that I, ANDREW A. SMITH, a citizen of the United States,residing at Hotchkiss, Delta-county, Colorado, have invented certain newand useful Improvements in Bob Sleds, of which the following is a full,clear, and exact specification, reference being had to the accompanyingdrawings, in which- Figure lis a perspective of the bob-sled.

Fig. 2 is a side elevation of the front sled.V

Figs. 3 and 4 are details.

The invention relates to that lclass of sleds or sleighs known asbob-sleds.

l The object of the invention is to provide a sled of this descriptionwhich shall be simple, strong, and durable.

The invention will first be described, and then specifically pointed outin the claims.

A is the front sled, B the rear sled, and C is the reach, vwhichconnects them adjustably. The front andrear sleds are constructed alikeand each consists in the transverse beam D, provided at its ends withdepending knees D', formed with a horizontal top cross-piece d, boltedto the under side of beam D, from the ends of which depend the side barsd' d', which converge toward their lower apertured ends, while from thefront and Arear edges of this cross-bar d extend the curved guides orguards d2, having a pair'of side flanges o r ears d3 at both ends.

E are the runners, formed of the flat steel shoes E', curved upwardly attheir forward ends and having wooden braces E2 on their upper sides.Each runner E is provided with a curved or segmental standard F, boltedat its ends thereto and having a perpendicular middle portion or braceF', formed at its lower end with a foot F2, bolted to the runner in acut-away portion e2 of the brace E2. The upper side of the brace E2 isrounding, and the ends of the standards F are provided with concave feetf, which rest upon the curved faces of the braces E2 and are bolted tothe runners. The knees D' straddle ythe curved standards F and arepivoted at their lower rounded ends by pivots f' to the lower end of thebraces F', said lower rounded ends resting on the upper sides of thefeet F2, so

5o that the whole weight of the load will be carried by the knees andnot strain the pivots f'. These pivots f' form the axes of the runners,and the curved standards and guards or guides d2 are concentrictherewith.

G are braces bolted to the beams D and to the forward ends of the guardsd2 to hold them rigidly in position, and thereby stay the standards Fand the runners against all lateral or twisting movement. f

The middle portions or braces F' of the curved standards F are eachformed of parallel plates bolted at their upper ends to the sides of thestandards and bent outward at their lower ends to form the foot F2; butsaid middle portion or brace F' may, if desired, be integral with thestandard F.

The knees D' are each provided with a pair of ears d4 on their forwardedges, and to the inner ears 67,4 of the rear knees are pivoted the rearends of a pair of braces H II, the forward ends of which are pivoted tothe ends of a tubular slide I, which slides freely on the reach C, thereach being provided with a longitudinal series of apertures c, throughwhich aperture in the top and bottom of the slide a pin i may be passed.The beam D of the rear sled carries a double nshape clip J, whichstraddles it and extends below it a sufficient distance to permit the`reach to pass through it and rest on its lower front and rearcross-bars j j. A pin K passes through an aperture in the middleof saidrear beam and through any one of 'the apertures o. Thus by removing pins1f K the rear sled may be adjusted longitudinally along the reach tobring it into proper relation to the front sled. All mortising of therear beam D is thus obviated by the use of the clip J.

The front end of the reach O extends under the beam D of the front sledand is there pro* vided with a draft-clevis L, which is formed of aplate bent upon itself and embracing the upper and lower sides of thesaid front end of the reach with its apertured rear ends. The upper sideof the said front beamvD is provided with an apertured wear-plate d,over which extends the front apertured end of the brace C', which isbolted atlits rear Aend to the upper side ofthe reach C. A

IOO

king-bolt L passes down through the front bolster M, the brace C, plated, clip L, and reach C and forms the axis onv which the front sled turnshorizontally. No rear bolster is necessary with my improved bob-sled.The bolster )I and the rear beam D are provided with any form ofstandards 711 forholding the load in place.

N is a curved brace pivoted er bolted at its middle between the twosides of the clevis L and at its ends pivoted or bolted to the innerears d* of the front bolsters D.

O is the tongue, pivoted at its rear end to the front end of the clevisL and provided with the usual draft attaclnnents.

O are two braces, secured at their forward ends to the tongue and attheir rear ends pivotally connected to the ears ny on the brace Nbetween its middle and ends.

rlhe operation and uses will be readily understood from the foregoingdescription.

It will be seen that as the knees D are each provided with two ears d*any knee will answer for either end of the beams D; also, that the uppersides of the beams D are wholly free from any projecting portions of therunner mechanism, as every part thereof is beneath the beams.

Having thus described the invention, what is claimed is- 1. Thecombination with the front and rear sleds, having cross-bars providedwith depending knees to which the runners are pivoted, of a reachextending under both beams and pivoted by a king bolt to the front beam,a double clip embracing the rear beam and extending down below its underside and embracing the reach with its sides or ends and lowercross-bars, and a pin passed through the rear beam and any one of aseries of apertures in the reach and between the front and rear crossbars of the clip and braces extending forwardly from the rear knees to aslide mounted adjustably on the reach, substantially as set forth.

2. In a bob-sled., the knee comprising a top cross bar adapted to bebolted to the under side of the beam, side arms depending therefrom andconverging toward their lower transversely apertured ends and theintegral guards or guides (l2 d3 projecting from the front and rear ofthe upper end of the knee and forming slideways for a curved runnerstandard, substantially as set forth.

In a bob-sled, the knee comprising a top cross bar adapted to be boltedto the under side of the beam, side arms depending therefrom, andconverging toward their lower apertured rounded ends, the front and rearguards or guides integral with the upper end of knee and the aperturedears on forward edges of the side arms, substantially as set forth.

(5. The combination with the runner having a segmental or curvedstandard of the beam-knee having side arms and integral oppositel yprojecting guards straddlin g the said standard and pivotally connectedat the lower ends of the side arms with the runner between the ends ofthe standard; the lower rounding ends of said side arms resting upon theupper side of the runner or an attachment thereof to take the strain oftoi.' the pivot, substantially as set forth.

7. The combination with the beam and the depending knees secured attheir upper ends to the lower side of its ends; said knees eachcomprising depending side arms havin g apertured rounded lower ends andthe integral oppositely projecting guards or guides at the upper end ofthe knees, of the runners, each having a segmental standard workingbetween the knee arms beneath the beam and provided with a middleportion or brace having a foot at its lower end secured to the runnerthe lower rounded ends of the knee being pivoted to the lower end ofsaid middle portion or brace and rocking on said foot, substantially asset forth.
